Use of bessel polynomials for solving differential difference equations

الملخص EN

In this paper, the linear differential difference equation subject to the mixed conditions has been solved numerically using Bessel polynomials.

The solution is obtained in terms of Bessel polynomials.

In addition, the accuracy and error analysis of the method are consid ered using residual function.

Some ecamples have also been considered to examine the applicability and reliability of the method.
